There has been some indications from IBM that there will be revisions of the 970 that lie somewhere between the 970 and the POwer5 derived chip. There is a very good possibility that the next generation may not be a Power5 based chip at all.
The pwoer5 based chip, what ever it is called at the time would become the basis for the G6. The G6 could very well mean a major revision to the motherboard. As such I don't think we will see the 970 based machines go away to soon.
That does not mean though that 970+ or 980 couldn't have significant enhancements. It is all a question of econmics and how fast Power5 derived hardware can be generated. Lets face it, it would not take much to enhance the 970 and generate significant pay offs. A larger cache for instance would do wonders as would and enhanced vector unit. Both of these enhancements can be handled without a major impact to the core.

I don't see why not. It is the next generation, and IBM have acknowledged that by calling the design on which it is based the Power5, the 980 is a derivitave of the Power5.
Jumping from the G5 to the G6 in just over a year would show the world that Apple is on the move. Intel moved quickly from the Pentium to the Pentum II. The 980 based machine is clearly going to be a much more compattitive machine thatthe G5. The G5 is intouch buit isn't all conquring. The G6 just might really have that crown.
